mortality/aging

craniofacial
abnormal parietal bone morphology ( J:94270 )
• ossification of the parietal bone is delayed
abnormal nasal pit morphology ( J:94270 )
• abnormally close association of the nasal pits
abnormal facial morphology ( J:94270 )
• facial midline defects are seen

skeleton
abnormal parietal bone morphology ( J:94270 )
• ossification of the parietal bone is delayed

nervous system
abnormal neuron differentiation ( J:94270 )
• the ventral midline cells are an intermediate state between pV3 and floor plate and fewer ventral progenitor cells are seen

respiratory system
abnormal nasal pit morphology ( J:94270 )
• abnormally close association of the nasal pits

cellular
abnormal neuron differentiation ( J:94270 )
• the ventral midline cells are an intermediate state between pV3 and floor plate and fewer ventral progenitor cells are seen

growth/size/body
abnormal facial morphology ( J:94270 )
• facial midline defects are seen
absent premaxilla ( J:94270 )

♀ phenotype observed in females

N normal phenotype
nervous system
abnormal neuron differentiation ( J:94270 )
• the reduction of pMN and pV2 progenitors results in a decrease in motorneuron precursors that are also abnormally positioned at the ventral midline
absent floor plate ( J:94270 )
• the floor plate is absent and the ventral midline has reduced numbers of the ventral most neural progenitors
